PAPER-BAG MACHINE.

SPECIFICATION forming part of Letters Patent No. 405,308, dated'J' une18, 1889. Application led August 13, 1888. Serial No. 282,549. (Nomodel.)

To a/ZZ whom it may concern: y

Beit known that I, ALBERT C. GETTEN, a citizen of the United States,residingat Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Paper-Bag Machines, ofwhich I do declare the following to bea full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of ro this' specification. v

A great desideratum with retail dealers and other users of paper-bags issome means whereby the mass or package of bags can be conveniently heldin such manner and posii 5 tion that single bagsy can be quickly takentherefrom without disarranging the package.

Appreciating this need, my present inventionhas for its object toprovide a paper-bag ma.

chine with means whereby the bags, as they 2o pass in finished conditionfrom the machine, shall each be furnished, at the same point withrespect to and adjacent` its open end, with a perforation or eut-awayspace, so that after thebags have been hunched together theseperforations 'will be coincident, in order to permit a suitablesustaining cord, rod, or wire Jrobe passed through the perforations tovconveniently hold a number of bags together and yet allow one or moreto' be readily re- 3o moved without disarranging the' others.

To this endmy invention consists in the novel features of constructionhereinafter decribed, illustrated in the accompanyingdrawings, andparticularly ydefined in the claims at the end of this specification.

' In the annexed drawings my invenhion is, for convenience,illustratedin connection with a paper-bag machine of the type illustrated inLetters Patent granted to C. B. Stillwell,

,o 'September 20, 1887, and numbered 370,099;

but it will be readily understood that it is applicable also to avariety of other machines.

Figure 1 is a plan view of ya portion of a paper-bag machine having myinvention ap plied thereto. Fig. 2 is a View in vertical longitudinalsection 0n line 2 2 of Fig. 1. Fig. 3 is a View of a portion of theformer detached. Fig. 4. is a perspective View of a finished bag,

showing the preferred location of the perfora- Y 5o tion. Fig. 5 is aviewl in vertical -transverse section on line 5 5 of Fig. 1. Fig. 6 isanenlarged view, in vertical transverse section, on

line 6 6 of Fig. 5. g v A designates the main frame of the machine,above the table or bed B of which is sustained the former C, which, inconjunction with the forming disks or wheels D, serves to fold the webof paper lengthwise as it passes tothe final folding apparatus. (Notshown.)

'The former C extends between the feed-rolls 6c E and E', and itsserrated edge terminates slightly beyond 'the fixed cutting-blade F, andwith this blade and the rotary cutting-blade or striker G co operates insevering 'thel folded tube into-suitable lengths to form the 6g finishedbags. The shaft G Iof the cuttingblade or striker extends obliquelyacross and beneath the bed of the machine and receives its rotation fromthe miter gear-wheel g,^the speed of which,ischangedaccording as it is7c desired to vary the length of the bags.

The general construction and operation of the parts as thus far defined,and aswell also their co-operation Withthe parts of the machine thathave not been shown, are well un- 7 5 derstood by-those familiar withvthis class of apparatus. f

The web of paper is by means of the former C vand'y forming-rolls `Dfolded into proper tubular shape to form a bellows-sidedv bag, 8o andthe folded .tube is severed' into proper bag-lengths by the fixed androtary cuttingblades and the serrated end of the former.

In order to provide each'bag near its top with a perforation,througliwhich acord,rod, or wire may be passed, I preferably employ a`punching mechanism consisting of rotary male and female dies. In theconstruction shown the male die His mounted upon a shaft I, held inbearings h above the table 9o and the former C, and the ,female die H ismounted on the shaft I', that is sustained by hangers J and J dependingfron. the under side of the table and attached to the main frame,respectively. The shafts I'and I' are 95 geared together, as shown, -andare in gear with the rotary cutting-blade or striker, the speed ofwhich'with respect to the feed-rolls determines the lengths of the bags.I prefer to gear the shaft I with the oblique shaft of roo the rotarycutting-blade or striker and to employ for this purpose sui-tablebevel-pinions 2 and 3, fixed, respectively, to these shafts.

My purpose in gearing the punchingmechanism with the striker is toinsure the accurate perforation of the paper adjacent the edge oftheparts that are to form the open ends of the bags, and it will be seenthat when the operation of the dies is once properly adjusted withrespect to the striker G the dies will continue to perfor-ate the paperat the proper points, it being only necessary to adjust'the movement ofthe dies with respect to the striker when the speed of the latter ischanged to form particular lengths of bags. This timing of the action ofthe dies with respect to the striker can be readily effected by theadjustment of the bevel-pinion 2 upon the shaft I (this pinion beingadjustably held on the shaft by means of a setscrew) until the strikerand the dies operate upon the paper at the proper relative times.

In order to enable the dies H and H to coact in perforating the paper, Iprovide the former C with a suitable space`as, for eX- ample, is shownat c-through which the dies can meet. This space c is preferably formedat such point andthe dies Hand II are preferably so placed that theperforation of the paper shall occur through the body and between thefoldedsides of. the tube and at one side of the pasted seam or lap, asseen inFig. l of the drawings. so placing'the dies that 'they hall cutthe paper atone side of the pasted seam or lap is not merely to avoidcutting through more than two thicknesses of paper, but also to avoidcutting through the paste and wet paper, which would interfere with themost effective action of the dies. My object, also, in so setting thefemale die II that it shall project through the former C in the punchingoperation is to avoid all danger of stretching or separating thefreshly-pasted seam of the folded tube, as would be apt to occur if theupper side ofthe tube were depressed in the punching operation.

In the particular form of .punching mecl1- anism shown, the shaft I, onwhich the male -die is mounted, is provided with a hole 4, ex-

tending through it, and with an offset 5, in which hole and offset thedie H isheld by means of a seat-block 6, threaded to engage with thethreaded lower portion of the die. in thus threading ,the rear portionof the' male die is to enable the die' to be readily adjusted from timeto time tocompensate for wear. Around the die I-I, I also preferto`place a rubber block 7, to enable the die to more certainly clear thepaper after the perforation has been made therein. The shaft I', thatcarvries the female die II', is shownA as provided with a disk`8,through which and the vshaft passes the transverse hole 9,- fromwhichthe -pieces punched out of the paper can readily 'falL It will beobserved that the female die pro My purpose in My object the paperdownward through the cutaway space of the former. It will be understood,however, that while I have described what I regard as the preferred formof punching mechanism, the precise details of construction may be variedwithin wide limits without departing from the spirit of my invention.

From the foregoing description it Will be seen that 'as the web of paperfolded in the direction of its length is fed forward between the dieslland Il', the perforation of the paper will be effected, and the movementof these dies will be so timed Awith respect to the rotation of thecutting-blade or striker that the perforation of the paper will occur ata point adjacent the line of cut of the cutting-blade or striker andconsequently adjacent the` open end of each bag. One advantage incidentto so gearing thepunchin g mechanism that its movements shall correspondwith that of the cutting mechanism is that a proper perforation of thepaper adjacent the line of cut subsequently made is thereby gearing thepunching mechanism is that the perforation of the paper is made whileitis still in the web, whereas, if attempt were made to effect thepunching after the baglengths had been cut, there would be seriousdanger of inaccuracy occurring'in the position of the perforations,since in the final folding operations a slight variation in the movementof the severed lengths is of frequent occur rence.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a paper-bag machine, the combination, with suitable rolls forfeeding the web of paper, a suitable former for folding the same, and aknife for cutting it into bag-lengths, of a punch for perforating thepaper, said punch being located in position to perforate the paperadjacent, but entirely at one side of the line of the top edge of eachbag,`substantially as described.
